Your examiners have to reach a decision, but it may be that they don’t agree on everything. It could be that one likes a particular idea or experiment or conclusion in your thesis and the other doesn’t. It may be that they can just work it out before they meet with you, but it could be the case that you have examiners who disagree with each other about something in the viva.
What do you do?
- First: listen and let them lay out their positions. You may have strong feelings for a topic, but let them talk first and see whether this is something you actually need to respond to. They may just be expressing different opinions, it may not be disagreement.
- Second: be sure of what you are responding to before you respond. If someone doesn’t like something, ask why. If they are vague, ask for details. Be clear and then respond as best you can. You don’t have to take sides, you just have to explain what you think.
- Third: if discussion results in corrections, get as much clarity as possible to see what’s involved. If there is disagreement about corrections between examiners, ask again for clarity.
Remember: it is not your job to resolve disagreements between your examiners. They’re professionals: expect them to be professional.
Wait for them to clearly state their points, then do what you can to engage with them and find out what (if anything) you have to do as a result.
